UNITED STATES DISTRICT COURT EASTERN DISTRICT OF MISSOURI EASTERN DIVISION

WENDY JENKINS, et al., ) ) Plaintiff(s), ) ) vs. ) Case No. 4:20-cv-01415-SRC ) NORTH COUNTY GENERAL ) SURGERY, et al., ) ) Defendant(s). )

Memorandum and Order Following a knee replacement in 2019, Wendy Jenkins developed an infection and ultimately lost her leg after several follow-up procedures. Wendy and her husband Richard sued a number of doctors and entities they claim negligently caused or contributed to the loss of Wendy’s leg. Following the Jenkinses’ settlement with the other Defendants, the Court denied Dr. Floro’s summary-judgment motion. Doc. 135. The Court now takes up Dr. Floro’s motions to exclude expert testimony, in which he invites the Court to arrogate to doctors the exclusive domain over expertise in such matters as, among other things, the costs of medical equipment, home modifications, and transportation. Docs. 100, 102. The Court declines the invitation. I. Background The Court has recounted the facts of this case in its Memorandum and Order regarding North County General Surgery and Dr. Floro’s (collectively, “Dr. Floro”1) summary-judgment motion, and does not repeat the facts here. See Doc. 135. In that Memorandum and Order the

1 The parties refer collectively to Dr. Floro and North County General Surgery, Dr. Floro’s single-member medical practice, and the Court follows suit. See Doc. 105 at p. 6; Doc. 113 at p. 7; Doc. 118-6 at p. 3. Court also explained some of the medical terminology at issue in this case and likewise does not repeat those explanations here. II. Legal Standard Federal law governs the admissibility of expert testimony in diversity cases in federal

court. Clark v. Heidrick, 150 F.3d 912, 914 (8th Cir. 1998). In Daubert v. Merrell Dow Pharmaceuticals, Inc., the United States Supreme Court interpreted the then-effective version of Rule 702 of the Federal Rules of Evidence to require district courts to be certain that expert evidence based on scientific, technical, or other specialized knowledge is “not only relevant, but reliable.” 509 U.S. 579, 590 (1993). The district court must make a “preliminary assessment of whether the reasoning or methodology underlying the testimony is scientifically valid and of whether that reasoning or methodology properly can be applied to the facts in issue.” Id. at 592– 93. Post-Daubert amendments to Rule 702 clarify the standard: A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if:

(a) the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;

(b) the testimony is based on sufficient facts or data;

(c) the testimony is the product of reliable principles and methods; and

(d) the expert has reliably applied the principles and methods to the facts of the case.

Fed. R. Evid. 702; see also Fed. R. Evid. 702 advisory committee’s note to 2000 amendment (“Rule 702 has been amended in response to Daubert v. Merrell Dow Pharmaceuticals, Inc., and to the many cases applying Daubert . . . .” (internal citation omitted)). The Eighth Circuit has fleshed out the Rule 702 standards. Proposed expert testimony must meet three criteria to be admissible under Rule 702. “First, evidence based on scientific, technical, or other specialized knowledge must be useful to the finder of fact in deciding the ultimate issue of fact. This is the basic rule of relevancy.” Lauzon v. Senco Prods., Inc., 270

F.3d 681, 686 (8th Cir. 2001). “Second, the proposed witness must be qualified to assist the finder of fact.” Id. (citation omitted). “Third, the proposed evidence must be reliable or trustworthy in an evidentiary sense, so that, if the finder of fact accepts it as true, it provides the assistance the finder of fact requires.” Id. (internal quotation marks omitted). To meet the third criterion, the testimony must be “based on sufficient facts or data” and be “the product of reliable principles and methods,” and the expert must have “reliably applied the principles and methods to the facts of the case.” Fed. R. Evid. 702(b)–(d). “Federal Rule of Evidence 702 reflects an attempt to liberalize the rules governing the admission of expert testimony.” Shuck v. CNH Am., LLC, 498 F.3d 868, 874 (8th Cir. 2007) (citing Lauzon, 270 F.3d at 686). The rule “favors admissibility if the testimony will assist the

trier of fact.” Clark, 150 F.3d at 915. Doubt regarding “whether an expert’s testimony will be useful should generally be resolved in favor of admissibility.” Id. (citation and internal quotation omitted). Under Rule 702, the trial court has gatekeeping responsibility to “ensur[e] that an expert’s testimony both rests on a reliable foundation and is relevant to the task at hand.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 141 (1999) (citing Daubert, 509 U.S. at 597). “When making the reliability and relevancy determinations, a district court may consider: (1) whether the theory or technique can be or has been tested; (2) whether the theory or technique has been subjected to peer review or publication; (3) whether the theory or technique has a known or potential error rate and standards controlling the technique’s operation; and (4) whether the theory or technique is generally accepted in the scientific community.” Russell v. Whirlpool Corp., 702 F.3d 450, 456 (8th Cir. 2012) (citing Daubert, 509 U.S. at 593–94). “This evidentiary inquiry is meant to be flexible and fact specific, and a court should use, adapt, or

reject Daubert factors as the particular case demands.” Unrein v. Timesavers, Inc., 394 F.3d 1008, 1011 (8th Cir. 2005). “There is no single requirement for admissibility as long as the proffer indicates that the expert evidence is reliable and relevant.” Id. As a general rule “the factual basis of an expert opinion goes to the credibility of the testimony, not the admissibility, and it is up to the opposing party to examine the factual basis for the opinion in cross-examination.” Nebraska Plastics, Inc. v. Holland Colors Americas, Inc., 408 F.3d 410, 416 (8th Cir. 2005) (quoting Hartley v. Dillard’s, Inc., 310 F.3d 1054, 1061 (8th Cir. 2002)). However, “if the expert’s opinion is so fundamentally unsupported that it can offer no assistance to the jury, it must be excluded.” Id. (citing Hartley, 310 F.3d at 1061). An expert opinion is fundamentally unsupported when it “fails to consider the relevant facts of the case.”
